samba - May 2006 - Servers disappear from Network neighborhood

I am using Samba-PDC-LDAP with samba-3.0.20b-1.  On my file servers I am 
using samba-3.0.10-1.4. 
I'm not sure exactly what is happening but every couple of weeks the 
file servers disappear form network neighborhood.  I checked browstat on 
my Windows system and it points to my PDC as the master browser and I 
checked the wins.dat file on my PDC and the systems were there.  I did 
not check the browse.dat file before correcting this latest problem (by 
restarting the nmbd service on the systems in question).  Is there a 
relationship between samba versions and systems dropping out of network 
neighborhood?  What does this indicate when a system drops out of 
network neighborhood, is it not reporting correctly to the master browser?

I had (and still do, really) a similar problem.  Has to do with nmb failing to
respond.  When they disappear, try running
"smbcontrol nmbd ping" on the samba server and see if it responds with
pong.

I have not yet figured out why nmbd stops responding.  The error logs have
offered no clue.  BTW, samba is running on SuSe SLES 9.

I am linux/samba newbie, so please take this with a grain of salt.  When I was
first trying to get my Samba PDC running, I was obsessed about Network
Neighborhood, and I spent a fair amount of time trying to understand how Samba
communicated that data back to the clients.  Based on what your describing, it
sounds like it could be master browser issue?  Maybe the PDC is having to fight
it out with the member servers to be the master browser.  I think the samba
options that can affect browsing are: os level, local master and domain master.

Here is some documentation on network browsing:

Hope this helps.
